HOPPER AN'D SPOUT CONSTRUCTION.

following is a specification.

The invention relates to apparatus for dis-' tributing concrete or othermaterialfrom a central point or station, and particularly to, the hopperand spout construction. The invention has for its primaryobjects theprovision of an improved swinging spout construction, (1) which ismaintained in proper registry with the hopper in all its positions ofadjustment, (2) which does not require accurate fitting or machine workto prevent the leakage of the concrete or other material, (3) which willnot become clogged up or get out of order, and. (4) ,which can be verycheaply constructed of ordinary commercial plates and angles. Oneembodiment of the invention is illustrated in the accompanying drawings,wherein- Figure 1 is a side elevation of my con- Struction, Fig. 2 is abottom view and Fig. 3 is an end elevation.

Referring to the drawings, A is the hopper to which the concrete orother material to be distributed is supplied; B is the spout for thehopper mounted for swinging movement so that its lower end follows thesegment of a circle formed by the angle irons C; D is a .hanclle builtup of angle irons and attached to the spout at its lower end forswinging such spout, the upper end thereof being guided along the angleiron segment E; and Gr, 1-1, I, K and L are re-. ceiving passages builtof sheet metal plates and having their inlet ends terminating at thesegment C so that the spout B may be 7 moved so that its lower end is inalinement with any one ofsuch receiving passages, the dot-and-dash linesM indicating the posi tion of the Spout when it is, in position todischarge to the passageway L. When the apparatus is used in connectionwith concrete the lower ends of the passages G, H, I, K and L areconnected to troughs or pipes leading to the various points at which theconcrete is to be used.

The hopper A is preferably constructed of sheet metal plates and has itslower end Specification of Letters Patent. Patented Mar. 12, 1918.Application filed July 15, 1916. Serial No. 109,579. i

terminating at the dotted line marked 1 in Figs. 1 and 2. The spout B isalso constructed of sheet metal and comprises front and back walls 2 and3 terminating L t the pivot rods 41- and 5, and side walls 6 and 7 (Fig.2) extending up to the line 8 (Fig. 1) somewhat above the lowerend 1 ofthe hopper. These side plates carry pivot members 9 and 10 pivotallysupported at the lower end of the hopper upon the transversely extendingangle beams 11 to which the upper endsof the segmental angle irons C areattached, such pivot members also having their outer ends supported inthe handle member D on one side of the spout and in an angle mem;

ber D on the other side of the spout (Fig; 2). otherwise secured attheir lower bent-in ends (Fig. 2) to the end of the spout.

The foregoing arrangement leaves open spaces in the spout above theupper edgesof thefront and back plates 2 and 3, and in order to closethese spaces and prevent a leakage of material between the hopper andthe spout when the spout is in all of its various positions, the closureplates 12 and 13 are provided, such closure plates being pivotallyconnected at their lower edges to the rods at and 5 and carrying attheir upper edges the rods 14 and 15. Each of the plates is held bythree straps 16, as indicated in Fig. 2, such straps lying on both sidesof the plates and extending around the two rods at their upper and lowerends. The rods 14 and 15 lie between and are guided by the inclinedangle members 17 and 18, and the inclined walls of the hopper A; Thespout is swung by means of the handle D, which handle is provided with apin 19 adapted to engage the various holes 20 in the segment E, so thatthe spout may be held in its various positions of adjustment.

It will be seen that by the provision of the closure plates leakage isprevented re-' gardless of the position to which the spout is swung, andthat this result is accomplished without the necessity of making anytight joints or accurately fitting the hopper and spout together. Thedevice is constructed of ordinary commercial sections and plates, andthere is no danger of clogging or of the parts getting out of order orcollecting and holding material in such a way as to interfere with theswinging of the The members D and D are riveted or spout. Otheradvantages incident to the simpliclty of my construction and its cheapness will be readilyapparent to those skilled in the art. I

What I claim is:

1. The combination with a tapering hopper having an open lower end, of aspout hinged at such lowerehdand receiving it,

closure plates hinged at their lower sides to the upper portions of thefront and rear' walls of the spout, guide members upon the exterior ofthe hopper, and guide means carrled by the upper sides of said platesand cooperating with the guide members on he walls of the spout, guidemembers upon the exterior of the hopper at the sides of the closureplates, and guide members carried at the upper portions of the closureplates and projecting to the sides thereof to engage said guide memberson the hopper, whereby the upper edges of said plates areguided to moveup and down the exterior of the hopper as the spout 1s swung back andforth.

walls of the sp bars extending along the upper edges of the plates andprojecting past the side edges thereof and secured o the plates, andguidescarried on the exterior hopper which the ends of said bars engageslidably whereby the upper edges of said plates are guided to move upand down the exterior of the hopper as the spout is swung backand forth.

4:. The combination with a tapering hopper having an open lower end, ofa spout hinged at such lower end and receiving it, closure plates,transverse bars at therupper and lower edges of the plates, strapsextending around the plates and bars for se curing the bars to the edgesof the plates, means for hinging' the bars at the lower edges of theplates to the upper front and rear walls of the spout, and guides uponthe exterior of the hopper with which the bars at the upper edges of theplates slidably engage.
